The Hawks announced the signing Friday.
Hunter was a first-round pick of the Boston Celtics in 2015 but has yet to make much of an impact, while also playing for the Chicago Bulls and Houston Rockets. He has averaged 2.6 points in 44 career games, with just one start.
Last season, Hunter was on a two-way contract with the Rockets, spending most of the season with Rio Grande of the NBA G League. He averaged 20.4 points per game in the developmental league, earning a shot with the rebuilding Hawks.
His father, Ron, is still the Panthers' coach.
